In gym-type clothing he was BEYOND a freak of size and leanness, a surefire bet to go pro, but when he got onstage, the hideousness of his shape, proportions, structure, etc. destroyed the dream.
At the time, from what I understand, the IFBB was not prepared to reward such a physique. His was a bit too much. Marketability? Not on your life.
A dozen or more years later and in the IFBB we're approaching Dave's level of "wrong". Branch is not quite there (yet?), but his physique is dangerously close to being pure and unbridled hideousness.
